What is the actual fuel tank capacity of the JAC S3?

The fuel tank capacity of the JAC S3 is 45L, which is the officially announced data. The JAC S3 uses 92-octane fuel, with a fuel consumption of 6.7L per 100 kilometers. A full tank can cover a distance of 671km. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank at all times. Generally, the fuel level is observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge on the dashboard usually has 5 to 6 segments. It is recommended to refuel when there are only 2 segments left to avoid running out of fuel midway. During the actual refueling process, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is measured from the bottom of the tank to the safety level, and there is still some space from the safety level to the tank opening. This space is reserved to ensure that the fuel inside the tank can expand when the temperature rises without overflowing. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

As a veteran driver who has been driving the JAC S3 for many years, I remember the official fuel tank capacity is 45 liters. A full tank usually lasts about 400 to 500 kilometers, depending on driving habits and road conditions. In city traffic with frequent stops and starts, fuel consumption is higher, resulting in shorter range. However, on highways, it's more fuel-efficient and can reach around 500 kilometers. When refueling, I often notice that after the pump stops, there's still room for an extra liter or two, but that's a safety margin—it's generally best not to overfill to avoid fuel spillage. The tank size is very convenient for daily commuting; a full tank can last over a week without needing to visit a gas station, saving a lot of time. For maintenance, regularly check the fuel cap seal to prevent foreign objects from entering and affecting performance, ensuring accurate fuel level calculations.

What Causes Mold Inside a Car?

The causes of mold inside a car may include moldy door panel soundproofing materials, moldy trunk molds, and moldy engine hood soundproofing. Below are detailed explanations and solutions: Moldy Door Panel Soundproofing Materials: In some low-end models, recycled materials are often used for soundproofing cotton. This material contains a large number of impurities, and after becoming damp and moldy, its soundproofing performance rapidly declines. Recycled soundproofing materials decompose when damp and moldy, producing a certain amount of formaldehyde, which poses a certain health hazard to occupants. The soundproofing materials in the four doors are the most severely contaminated parts in the cabin, necessitating the replacement of the door panel soundproofing materials. Moldy Trunk Molds: The molds are located on the lower deck of the trunk. Some cars with poor sealing performance may accumulate a certain amount of water in the lower part of the trunk. Covered with a thin layer of sponge, this sponge has a certain water-retention capacity. Mold mainly concentrates on the sponge and the lower trunk, requiring the removal of moisture from the car's interior molds. Moldy Engine Hood Soundproofing: Many car models now have a layer of soundproofing on the engine hood to reduce noise and vibrations produced by the engine. The soundproofing material on the engine hood is usually quite thick. After the engine heats up, condensation during the rainy season can cause moisture to be absorbed by the soundproofing walls, requiring the wiping of moisture from the engine hood.

What to Do If You Fail the First Attempt in Subject 2 and Need a Second Try?

Maintaining a slow speed is the fundamental rule for practicing Subject 2. Ensure the vehicle doesn't stop while keeping the speed as slow as possible—the slower, the better. After getting into the car, always adjust the rearview mirrors properly, which is especially crucial for reverse parking and parallel parking. The three key points are the driver's eyes, the reference points on the car, and the reference points on the ground. During the operation, you must accurately identify these points and observe them carefully to ensure precision. During reverse parking, the front corner tends to brush against the outer boundary line, while the rear corner may brush against the side lines of the parking space. Similarly, the front corner may cross the line during curve driving. Therefore, pay close attention to the four corners and the outer boundary lines.

How to Change Clutch Fluid?

Prepare a hose and a glass container with clutch fluid. Connect one end of the hose to the bleeder screw and immerse the other end into the glass container filled with clutch fluid. Open the bleeder screw. Fill the master cylinder reservoir with clutch fluid until no bubbles emerge in the glass container, then tighten the screw; check the clutch pedal free travel. After tightening the bleeder valve, release the pedal. Continue bleeding until fresh clutch fluid enters the container without any bubbles.

How to Remove the Ignition Lock Cylinder on an Old Sagitar?

There are a total of 5 cross-head screws at the bottom; remove them to see inside. The cover is divided into upper and lower parts. The right side of the lower part is fitted over the ignition switch and needs to be detached before it can be removed. This is a hex socket screw, so you'll need a hex screwdriver. The screw holes can be seen above the turn signal lever and the wiper lever, with one on each side. There is a clip on the connector; be sure to detach it first. The lock cylinder cannot be unscrewed or pulled out directly; there's a trick here. Turn the key to the "B" position, and then it can be pulled out.
